Today's test was another major failure.

Judging from Ma Yuanjian's unusual behavior, Ling Xiuqi concluded that the other party must be related to this matter, and then his attention fell on Director Dai.

Although he didn't know why Ma Yuanjian attacked him, Ling Xiuqi was certain that Director Dai knew something.

Director Dai did not wake up until You Yonghuai found a large enough bag to put Li Gui's human skin inside.

"What did you do to him?" Ling Xiuqi asked, supporting Ma Yuanjian.

"you guess."

"Hey, there's something in the men's restroom~" Si Xuanyin suddenly floated out and said.

Because she has no physical body and ordinary people cannot see her, Si Xuanyin's adventurous spirit is stronger than ever before.

In other words, he really likes to go to places that are "not for women".

For example, an empty men's restroom.

Since Ling Xiuqi also had to keep an eye on Ma Yuanjian, he turned around and asked You Yonghuai to take a look.

You Yonghuai returned quickly, but without bringing anything with him: "There is something there, but I can't get it."

"What do you mean?"

"There was a syringe that fell into the toilet and wasn't flushed down."

Ling Xiuqi's lips twitched.

Ma Yuanjian's eyes widened.

"Why is it a syringe again..." Seeing Ma Yuanjian's surprised expression, Ling Xiuqi felt even more disheartened and tentatively asked, "Are you also from the Infernal School?"

Ma Yuanjian was panting heavily.

"What are you saying? I don't understand." The man, who was nearly fifty years old, turned his head away and said with a pale face.

"Has anyone ever said that your poker face is bad?" Ling Xiuqi called his colleagues again, telling them to bring extra gloves when they came, and to send only those who weren't afraid of getting dirty.

After the two police officers arrived and, amidst the curious gazes of the students on the first and second floors, hurried up to the third floor, Ling Xiuqi calmly began assigning tasks:

"Xiao Zhang, take this unconscious person to the hospital for a full check-up."

"Xiao Li...aren't you afraid of getting dirty? Go to the third stall in the men's restroom and take the syringe out."

"?" Xiao Li's pupils dilated in shock. He opened his mouth slightly, but before he could utter a word of refusal, Ling Xiuqi kicked him in the butt. "Go now!"

After putting the wet syringe into another evidence bag, Ling Xiuqi called a car for Xiao Zhang to take him and Director Dai to the hospital, while he himself went with Xiao Li and You Yonghuai to escort Ma Yuanjian back to the police station.

"Oh my god, Director Dai is dizzy, Principal Ma has been arrested. I knew it! Why would we build a school on someone else's grave?"

Ling Xiuqi glanced back at the senior high school student behind him, who was talking eloquently, but didn't pay much attention.

Back at the police station, Xiao Li, who had already washed his hands once at school, went to wash them a second time. It's estimated that he won't be leaving the sink anytime soon.

Ling Xiuqi didn't rush to interrogate Ma Yuanjian. After ordering his men to lock him up, he handed out several evidence bags.

Photos of the magic circle were sent to headquarters, hair samples were sent for DNA testing, and syringes were mailed back to headquarters for examination...

When explaining the situation, Ling Xiuqi hesitated for a long time, making You Yonghuai think that something was missing. It turned out that he was hesitating about whether to tell the team leader that the thing was taken out of the toilet.

Finally, he decided to have the team leader call him after he got the syringe, so he could personally give him instructions.

As for Li Gui's human skin, he cut off a portion and sent it for examination.

He was afraid that sending such a thing would frighten the doctor.

After You Yonghuai and Ling Xiuqi had lunch together at the police station, the test results were released.

The human skin was Li Gui's skin, but the owner of the hair was someone else that surprised You Yonghuai.

That strand of hair belonged to Huang Li, who was Si Xuanyin's mother.

"There's another thing," Ling Xiuqi said, reviewing the statements taken by other classmates when Wei Haiping jumped off the building. "Li Gui's classmates said that he hasn't grown taller in the past two years; he's always been 1.66 meters tall."

"This is my mom's height..." Si Xuanyin's lips twitched.

"And your mother has been missing for two years." You Yonghuai didn't know whether to laugh or not. "So she's been pretending to be a high school boy for the past two years? That's too bizarre."

"No, aren't his family members surprised by the change in his personality?" Si Xuanyin held her head in her hands, finding it hard to accept.

The urge to kill his mother grew stronger.

"Maybe they think the child has reached puberty?"

"Perfect timing, I'll make a call and ask." Ling Xiuqi entered a number on the landline on his desk and said, "The child's body has been found... well, at least halfway, we definitely need to notify the family about this."

As he spoke, Ling Xiuqi dialed a phone number.

"Hello, what's up?" A cold female voice answered the phone.

"Hello, this is the police station. Are you Li Gui's parent? We have some very unfortunate news... We have found your child's body."

"oh."

"Um, why don't you come over sometime to identify him... no, your child's death was horribly tragic, but..."

Before he could finish speaking, Li Gui's parents interrupted, "There's no need. If you want to use it for investigation, go ahead. After you're done, just cremate it."

Ling Xiuqi looked incredulous. When Li Yongqi told him that Li Gui's parents didn't care about this matter, he didn't really understand. But now he really didn't understand.

No, is it really this uneventful that the child died?

"May I ask you one more question?"

"……you say."

Did your child experience any significant personality changes during the transition from junior high to high school?

"Why are you asking this?" Only now did Li Gui's voice show any noticeable change.

"We suspect that Li Gui has been impersonated for two years," Ling Xiuqi said in a serious tone, while simultaneously sending a message to You Yonghuai on his phone.

You Yonghuai glanced at it and instantly understood. He imitated the other police officers' efficient voices, stomped his feet a few times, and announced loudly, "Captain Li, the suspect Huang Li has been apprehended."

While You Yonghuai was speaking, Ling Xiuqi deliberately handed him the phone to ensure that the person on the other end could hear.

"This is absolutely impossible!" Li Gui's parents' voices suddenly became agitated. "How could we not recognize our own child? How could Li Gui be impersonated?!"

"I'm so sorry, so sorry," Ling Xiuqi said in a very apologetic tone. "We made a mistake, we're really sorry."

"snort!"

After hanging up the phone, Ling Xiuqi operated the computer and began to track down Li Gui's parents' phone number.

As he expected, the number made another call within minutes.

Ling Xiuqi narrowed his eyes, copied the number, searched the database, and easily obtained an address.

"Let's go," Ling Xiuqi said with a smile, grabbing his coat from the back of the chair. "Let's see if Li Gui's parents really have any problems."
